In last years, the challenge of providing end-to-end service where end-to-end forwarding paths do not exist is faced by the new emerging approach of Delay Tolerant Networks (DTNs), that support interoperability of “regional networks” by accommodating long delay between and within regional networks, such as space communications, networking in sparsely populated areas, vehicular ad-hoc networks and...
In this paper a variant to epidemic propagation scheme applied to Delay Tolerant Networks (DTNs) is proposed. It extends the approach proposed in the basic epidemic routing and adopts the forwarding scheme of the n-Epidemic routing. However, differently from n-Epidemic, it applies a dynamic forwarding scheme based on nodes density that is able to reduce energy consumption and increase message delivery...
